Recently, excavation of ancient pottery kiln of Koryo celadon of the Koryo dynasty have been continued since 1979 in Hang-dong, Daegu-myun, Gangjin-gun, Jeonnam Province, south-western part of Korea. The authers carried out an archeomagnetic study using the baked earth of the floors of the kiln, togimi and fabrics of rocks which were placed firmly on the floors of the kiln. These specimens were measured using the astatic magnetometer. The results of measurements are: declination, $0.3^{\circ}W$; inclination, $52.9^{\circ}C$. Referring to the secular change curves drawn from the studies of the south-western Japan, the last period when the pottery kiln was fired finally is estimated to be around A.D. 1170. Many potsherds of Koryo celadon were excavated around the kiln. According to the shape of these potsherds, the age of the pottery kiln is estimated to be 10-12 C, which is consisted with this study.

The author has observed the gross reactions of surrounding maxillary sutures to the widening of midpalatal suture in comparison of young dog with adult dog. Experimental animals used was two young dog and two adult dog with normal palate. After midpalatal suture was seperated with rapid palatal expansion device, experimental animals were sacrificed to observe the surrounding maxillary sutures. The following results were obtained. 1. In adule dog, nasoincisive suture was not expanded, while in young dog it was espanded. 2. In adult dog, pterygopalatine suture was hardly espanded, while in young dog it was expanded unilaterally. 3. In adult dog, frontomaxillary suture was not expanded, while in young dog it was expanded unilaterally. 4. In adult dog, palatoethmoidal suture was not expanded, while in young dog it was expanded unilaterally.

Background: There is no report on the actual conditions and current educational status of dermatopathology in Korean the literature, implying that the interest in dermatopathology, which is important in clinical practice, is drawn away. Objective: This study was performed to investigate the actual conditions of dermatopathology. Based on the collected data, we could set up the directions for the development of dermatopathology. Methods: From April to June 2012, we conducted a survey of 62 dermatologic training hospitals and 328 residents working in the dermatology department in Korea, respectively, by mail, anonymously. Results: Residents` satisfaction of current dermatopathology education was significantly higher in tertiary hospitals and in hospitals with numerous dermatologists. The number of performed skin biopsies per week was also significantly larger in tertiary hospitals. Of tertiary hospitals and hospitals with numerous dermatologists, lectures given by dermatologists or dermatologists specialized in dermatopathology took a higher proportion in the dermatopathology course, and in-hospital dermatopathology conferences were held more than 5 times a month. Conclusion: As shown in the result of this survey, to enhance interest in dermatopathology, we suggest activation of the Korean society for dermatopathology and joint conferences among local hospitals.

This paper presents ion-based micro vibration sensor for the ultra-high frequency vibration detection. Presented sensor uses the motion of anion and cation in an electrolyte. Electrolyte vibration sensors have the high shock survival characteristics and a simple read-out circuit because of the small mass and own charges of ions. Presented sensor measures the induced electric potential by the mechanical-electrical coupling. It consist of electrolyte chamber and detection electrode. Electrolyte chamber was fabricated by PDMS molding. Detection electrode was made of gold evaporation on pyrex glass. Size of electrolyte chamber was designed as 600×600×100㎛. Detection electrode had 200㎚-thick and 42㎛-gap. In the experimental study, 5.8M sodium Chloride (NaCl) solution was used as electrolyte in 36nl-chamber. Mechanical vibration was measured from 2kHz to 4㎒.

Two ellagitannins, pedunculagin and 2,3-(S)-Hexahydroxydiphenoyl (HHDP)-D-glucose and three condensed tannins, (+)-catechin, (-)-epicatechin and procyanidin B-4 which were isolated from Rubus coreanum were evaluated for their antioxidative effects with 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and lipid peroxidation generation system mediated by addition of H202 to rat liver homogenate (TBARS). The ellagitannins, 2,3-(S)-HHDP-D-glucose and pedunculagin, showed more potent antioxidative activities by DPPH and TBARS than condensed tannins.
